Thaum engineers qhia a cpp peev casting Hoobkas, lawv tsis yog tab tom nrhiav rau lwm qhov chaw - lawv tab tom nrhiav kev ruaj ntseg nyob rau hauv thermal cycling, microstructural sib xws hauv AMS 5387 cobalt alloy, thiab xoom kam rau porosity hauv lub tog raj kheej lub tog raj kheej ntsuas rau 400+ bar. Qhov ntawd yog qhov kev ua haujlwm tiag tiag peb pom txhua hnub ntawm Qingdao Qiangsenyuan Technology Co., Ltd.—ib qhov chaw uas peev casting tsis yog ib qho txheej txheem tab sis ib qho nruj ua ke nrog ntau-axis CNC machining, kev kho cua sov teem caij, thiab GD & T-tsav tshuaj xyuas.
Vim li cas "CPP" txhais tau ntau dua li ib qho lus luv luv xwb
"CPP" sawv cev rau * Cobalt-Precision-Twj * - tsis yog kev lag luam tagline, tab sis kev ua haujlwm triad kos rau hauv txhua qhov kev txiav txim. Peb tau pom cov neeg siv khoom nkoj kos duab kos npe "AMS 5387, RMA 40, ± 0.02 hli" tsuas yog txhawm rau tshawb pom qhov nruab nrab ntawm cov khoom lag luam uas lawv tus qauv tsim tsis suav nrog kev ua kom muaj zog hauv lub cev nyias nyias. Qhov ntawd yog thaum CPP hloov los ntawm cov ntawv luv rau kev nqis tes ua: peb cov metallurgists kho gating geometry; peb cov machinists rov ua ntu ntu ntu ntu kom khaws cia raws li-cam khwb cia saum npoo kev ncaj ncees; peb pab pawg QA validates hardness gradients thoob plaws tshav kub-cuam tshuam cheeb tsam - tsis yog nyob rau saum npoo.
Qhov no tsis yog theoretical. Xyoo tas los, European hydraulic OEM tau xa peb lub piston twj tso kua mis vaj tsev nrog peb qhov kev sib tshuam bores, txhua qhov yuav tsum tau ua tiav qhov sib txawv (Ra 0.4 µm ntawm lub ntsej muag sealing, Ra 1.6 µm ntawm qhov chaw mounting). Txoj kev xyaum yuav tau nrum ntxhib, ces tshuab txhua yam. Hloov chaw, peb siv peev casting los xa cov duab nyob ze ntawm ob lub bores - thiab tsuas yog siv lub thib peb, qhov uas siv nruj tshaj plaws. Lub sijhawm voj voog poob 37%. Tus nqi seem poob los ntawm 11% mus rau 1.8%.
Plaub Muaj Peev Xwm Uas Sib Nrauj
Ntau tus neeg muag khoom sau "casting + machining + finishing" raws li cov kev pabcuam cais. Ntawm peb lub chaw Qingdao, cov haujlwm no qhia cov cuab yeej siv cov ntaub ntawv, cov ntaub ntawv keeb kwm thermal, thiab CMM sojntsuam cov sijhawm teem sijhawm. Nov yog qhov nws ua haujlwm hauv kev xyaum:
- Casting tswj pib ua ntej pouring: Peb txheeb xyuas cov ntaub ntawv pov thawj raw khoom rau T800 alloy tiv thaiv ASTM A992 - tom qab ntawd hla kev txheeb xyuas spectral tsom xam tawm tsam cov khoom lag luam batch. Tsis muaj kev zam.
- Machining compensates rau casting variation: Peb Haas VF-6 mills siv cov cuab yeej siv sijhawm tiag tiag hnav cov nyiaj them nyiaj, pub los ntawm cov txheej txheem laser scanning ntawm qhov tseem ceeb datum nta - yog li yog tias lub casting khiav 0.015 hli oversize ntawm lub ntsej muag flange, lub zeb kho qhov tob-ntawm-txiav txiav.
- Kev kho cua sov yog teem caij - tsis ntxiv: Thaum lub cobalt alloy plug yuav tsum tau tov annealing ntawm 1150 ° C ± 5 ° C, peb tsis outsource. Peb lub tshuab nqus tsev vacuum teev txhua qhov kev nyeem ntawv thermocouple, thiab cov ntaub ntawv syncs ncaj qha mus rau ib feem ntawm cov ntxaib digital hauv peb MES.
- Ua kom tiav qhov sib tw ua haujlwm, tsis yog cov ntawv tshwj xeeb: Lub winch center ncej cov menyuam tsis xav tau Ra 0.8 thoob plaws nws qhov ntev-tsuas yog ntawm 42 hli tiv tauj band. Peb npog qhov chaw tsis tseem ceeb thiab siv electro-polish xaiv.
Dab tsi cov neeg siv khoom sim tiag tiag - Tsis yog Daim Ntawv Teev Npe Thov
Qee tus nug: "Koj puas tuaj yeem tuav ± 0.015 hli ntawm 320 hli cobalt alloy valve lub cev?" Yog - tab sis tsuas yog yog tias daim duab piav qhia qhov ntsuas qhov nruab nrab txheeb ze rau cov qauv tsim datum, tsis yog CAD keeb kwm theoretical. Lwm tus xav tias "stainless hlau casting" txhais tau tias 316L. Tab sis nyob rau hauv high-pressure roj & roj kev pab cuam, peb default rau CF8M tshwj tsis yog hais tias lwm yam - vim hais tias nws cov ntsiab lus ferrite tswj kev ntxhov siab corrosion cracking kuj nyob rau hauv qaub ib puag ncig.
Peb tau muaj peb North American cov neeg siv khoom xa rov qab - tsis yog rau qhov tsis ua haujlwm, tab sis vim tias lawv cov kab sib dhos cov neeg hlau gripper plam ntawm qhov chaw tiav uas tau ntsib Ra specs tab sis tsis muaj qhov xav tau micro-kev ntxhib los mos rau coefficient ntawm kev sib txhuam. Tam sim no, peb suav nrog profileometer scans hauv txhua pob PPAP rau cov khoom siv thauj khoom. Tsis yeem. Tsis sib tham.
Qhov twg Precision ntsib qhov kev xa tawm
Ib qhov tseeb cpp peev casting Hoobkas yuav tsum sib npaug metallurgical nruj nrog kev qhuab qhia ntau lawm. Qhov ntawd txhais tau hais tias tuav ISO 9001: 2015 ntawv pov thawj thaum tseem tab tom khiav txhua hnub kev tshuaj xyuas kaizen ntawm cov xuab zeb rov qab nqi hauv peb lub tuam txhab peev plhaub - lossis taug qab cov txiaj ntsig thawj zaug ntawm AMS 5387 nozzles hla tsib lub tshav kub sib law liag kom pom qhov sib txawv me me hauv cov nplej loj.
Peb pab cov neeg muas zaub los ntawm Hamburg mus rau Houston mus rau Ho Chi Minh City - tsis yog los ntawm distributors, tab sis los ntawm ncaj qha engineering tshuaj xyuas. Txhua nqe lus suav nrog cov lus qhia txog kev tsim khoom: "Lub vojvoog fillet no yuav ntxiab ceramic residue-pom zoo R1.2 min." "Cov qhov muag tsis pom no tshaj qhov piv txwv txwv rau lub plhaub pwm venting-qhia thru-qhov nrog ntsaws." Tsis muaj jargon. Tsis muaj deflection. Tsuas yog cov tswv yim ua tau zoo, xa hauv 72 teev.
Saib tom ntej, peb lub hom phiaj tseem nyob qis qis: kev paub tob tob ntawm cobalt-nickel systems, kev sib xyaw ua ke ntawm kev simulation thiab CNC toolpath tiam, thiab nthuav dav AS9100 rau kev sib tw aerospace-qib twj tso kua mis. Vim tias qhov tseeb tsis ntsuas hauv microns ib leeg - nws tau ua pov thawj hauv lub sijhawm ua haujlwm, rov hais dua, thiab kev ntseeg siab ntawm tus kws ua haujlwm uas paub tseeb tias yuav ua li cas thaum molten T800 tsoo pwm.
